Pros
Pro It has sculpting and 3D painting features
Although blenders 3d painting and sculpting tools (mostly painting) are not at par with specialized software like Substance painter, z brush, or mari; it is more than capable of getting most jobs done if the user takes the time to learn and understand it.
Pro Very useful for a freelancer.
It offers a round solution (it covers many areas and professional fields) for a freelancer, for free, constantly updated, very polished, and allowing high quality results that clients do require. After some learning, it becomes very useful for professional work.
Pro Has a good rendering engine
Blender runs the Cycles path tracing engine under the hood. Cycles is a very powerful rendering engine capable of full path tracing (light fall off, caustics, volumetrics). It is mostly compatible with OpenCL and CUDA rendering, and is implementing mycropolygon displacement features.
Pro Includes a complete game engine
Blender has a complete game engine. It features node based scripting (called Node Editor), Python scripting, dynamic shadows, bullet physics, animated textures and more. Combine it with the ability to model, render bake and texture paint inside the same application and modify the source code because of it being free and open source, Blender becomes an excellent choice for making prototypes and even complete games in considerably low amount of time.
